JOHANNESBURG - A heavily-armed Ugandan military convoy has crossed into South Sudan to evacuate citizens trapped by recent fighting in the capital, Juba.

Intelligence sources in Entebbe says some of them will stay behind once they've got their compatriots out.

The Uganda operation comes as a ceasefire between the divided forces of President Salva Kiir and Vice President Riek Machar goes into a third day.

Nevertheless, the United Nations says it fears fresh fighting is inevitable in Juba.

The Ugandan army convoy of around 50 lorries escorted by machine gun-mounted armoured vehicles crossed into South Sudan at Nimule this morning.

They're opening a corridor to Juba 200kms away where the fighting has killed more than 300 people.
